' lies in the fact that'looseness atthe pivotal, connection would resultin displacement, of 59 the opening devicef rom thefclosure, whenthedevice wasoperatedfor the purpose of;

Furthermore, i the -fianges, of'beads, engaged bysuchiold 'devices were so formed that the opening device "F145, lwaslikely to be displaced therefrom'atfthe beginning of theopeningoperation, and the 7 old opening devices carried by the:containers" vliverealso subject, to the danger of being ac p cidentallybent and thereby-fenderedinop- V fi iyerative. v in "amnes aseren ty 3,

closure seat 2 at its upper mar in, and a flat,annular twoplyperipheral, ange 3 ns clined upwardly from the bottom of said metal. Theinner faces of the plies ofeach flange preferably contact with eachother,

as this produces a strong flat'fiange which: materiallyreinforces thecontainer, and the".

, outer edgeof the;flange is relatively sharp;

so it-will not tendEto displace a screwdriver,

However, in the preferred form ofthis invention-, the open2ngdev1ce1scarried by i the container, and to illustrate this feature I I havefihoWn-a lever 6rpivoted at 7.;to the body member 1, and, providedwith-a thrust element 8 confinedbetween thejinner face of the flangedand the container, wall formed a by the lower marginof theclosure. The

lever-6 .has a linger-receiving member 9 which may be depressed toelevate the/thrust member ,8, and sincethis thrustmember is con- .finedby theinclined flange 5, it cannot be displacedduring the openingoperation.

This practically eliminates the liability of displacemenhand insuresthedesired open- 7 ing of the containerwhen the requiredforceisappliedjo the opening device.

Asa further safeguard, to prevent -accidental bending, or displacement,of the thrust element of theop ening device, the lever 6 may be providedwith a, downturned retaining ale-- tively prevent displacement of thethrust member 8 of the opening device.

Sincethe'opening device can be securely interlocked with'the container.it is not absolutely necessary toprovide any other means to secure saiddevice, and as'a simple illustration of this feature I have shown, inFig.

4a lever iiwhichis not pivoted to the con tainer. This lever may in allother respects conform tothe lever shown in Figures 1, 2

and 3-, but'of course other formsof opening devices conforming tothe'following claim m'aybe interlocked with the container, or thespecific flange arrangement may be advantageouslyused with any othersuitable opening device. o 7
